The Adolescent Medicine Clinic at Children's Hospital Colorado offers a full range of primary, secondary, and tertiary health care to teenagers in the Denver metropolitan area. Consultative services are provided to adolescents with complex physical and emotional problems who are referred from throughout the Rocky Mountain area.

The Eating Disorders Program at Children's Colorado is recognized nationally for the management of complicated cases, providing both inpatient and outpatient services.

The Colorado Adolescent Maternity Program (CAMP) at Children's Colorado is a multidisciplinary prenatal and postnatal program that addresses three critical issues in maternal and child health: the frequency of late, inadequate prenatal care; the large number of preterm births; and the high rate of recidivism, school failure, and welfare dependency among adolescent mothers and their children.

The Pediatric and Adolescent Gynecology Clinic at Children's Hospital Colorado includes a multidisciplinary team of pediatricians and gynecologists with expertise in evaluating abnormal Pap smears; chronic lower abdominal pain; amenorrhea and dysfunctional uterine bleeding; persistent vaginitis; dysmenorrheal; and they provide contraception for those with chronic diseases.

The Adolescent Family Planning Clinic, BC4U (Birth Control for You), is a new expanded program offering free birth control methods to adolescents and young adults. Although both the Adolescent Medicine and Young Mothers Clinic have always provided birth control services to teens, through expanded Title X funding, we have opened this new clinical service with outreach into the community. The program is focusing on long acting contraception, IUDs, Implanon and Depo-Provera. Our goal has been to develop a model of family planning care for adolescents and young adults that will improve their knowledge of and access to contraception and increase awareness to adolescents in our community who are currently unaware of the family planning services we offer. We have three locations that these services are offered at:

Children’s Hospital Colorado Hospital
13123 E 16th Ave
Aurora, CO 80045

Littleton Specialty Clinic
151 W County Line Rd
Littleton, CO 80129

Care by Children’s Hospital Colorado
3455 Lutheran Pkwy
Wheat Ridge, CO 80033

Pediatric Clerkship

Adolescent Medicine is an important part of the pediatric clerkship curriculum for third-year medical students at the University of Colorado School of Medicine. Our faculty provides a lecture in adolescent medicine as part of the clerkship's core lecture series.

Medical School Elective

An elective in adolescent medicine is available for fourth-year medical students who have successfully completed a pediatric clerkship.


Clinical training during residency includes experience with primary adolescent health care and specific problems common during adolescence, including abnormalities of growth and development; orthopedic and sports medicine problems; issues relating to sexuality and reproductive health; psychosocial, mental health, and substance abuse problems; and the management of teenagers with chronic illnesses and recurrent somatic symptoms.


The University of Colorado School of Medicine Department of Pediatrics and Children's Cololrado offers a one- or three-year fellowship in adolescent medicine. The fellowship is accredited by the Accreditation Council of Graduate Medical Education. The goal of the fellowship is to provide physicians who are board eligible in pediatrics, internal medicine or family medicine with in-depth training in adolescent medicine that will prepare them for a career in clinical or academic medicine.
